This model is ready to fly..sans engine. It is set up for an OS 120 which will fly it very well. It is a kit built aircraft covered very nicely in fabric and painted. I upgraded it last summer with a new 22 oz. tank, 2200 mah batt, switch and new control equipment between servos and surfaces. Very nice Cub in excellent condition....just not my bag anymore. Also willing to trade for an Old Timer or such kit. Merry Christmas, Neal
